PIPE-COUPLING.

SPECIFICATION forming part of Letters Patent No. 451,565, dated May 5,1891.

Application filed December 14, 1889. Serial No. 833,738. (No model.)

.To all whom it may concern:

Be it known that I, JOHN IV. MOORE, of the village ofLansingburg,countyof Rensselaer, State of New York, have invented newand useful Improvements in Couplings for Hose and Steam PipeConnections, of which the following is a specification.

My invention relates to improvements upon that class of couplings whichare used to connect hose and also the steam-pipes employed for heatingthe cars of railway-trains, and the purpose and object of my inventionis to construct each of the coupler parts oppositely alike, and so thatone will connect with the other without using an intermediate shortD19@- Accompanying this specification to .form a part of itv there aretwo plates of drawings containing eight figures illustrating myinvention, with the same designation of parts by letter-reference usedin all of them.

-In the illustrations, Figure l is a side elevation of my improvedcoupler with the parts shown as connected with one of the clampinglipsand catches of each coupler parts shown as' connected with the oppositeclamping-lip and catch part of the other, and With each of thescrew-bolts 'arranged oppositely in subtending or overlapping arms uponeach of the coupler parts also shown. Fig. 2 is another side elevationof the parts illustrated in elevation at Fig. 1, with the clamping-lipsand catches connecting the two coupler parts, said figure illustratingalso one of the screw-bolts. Fig. 3 is an end elevation of one ofthecoupler parts with its bearing or packing face turned facing theView. Fig. 4 is a cross-section of one of the couplerparts, takenthrough one of the clamp-lips, one 'of the arms, nuts, and bolts, andpipe or hose, on the line 0c a of Fig. 3. Fig. 5 shows the same partsthat are shown at Fig. l, but with a modified means for operating thescrew-bolts to adapt my invention to connect the steam-heating pipes ofa railway-train. Fig. 6 is a section taken on the line m2 x2 of Fig. 5.Fig. 7 is a side elevation of the modification shown at Figs. 5 andG asapplied to connect the steamheating pipes .of two cars. Fig. 8 is a topView of the apparatus shown at Fig. 7.

The several parts ,of the apparatus thus illustrated are designated byletter-reference, and the function of the parts is described as follows:

The letters O and Ozdesignate the coupler parts, each of which isoppositely made with a central )assage O2, and each of them made with aflange F', encircling said passage, a tail-piece V, and a beveledsurface B on the outside of said iiange where joining the tailpiece.Each of these coupler parts is made with a face F2, containing packingadapted to make a steam and water tight joint when these faces ofthe twocoupler parts are brought together in abutting Contact and secured insuch position.

Theletter W designates wedge-form catches that are projected radiallyfrom the outer surfaces of the flanges F of each coupler part, and theletters L designate lips that are also projected therefrom, which lipsof each coupler part are made to overlap the Hangerim of the othercoupler part where the two are brought together for connection, and eachof these lips is made with a slot gon its side where facing the catchpart of the other coupler part. When the coupler parts as thusconstructed are brought together with their packing-faces in contact andare slightly rotated, so that the lips will approach the wedgeformcatches IV, the latter will enter the slots of the lips to tonguetherein, while the wedgingfsurfaces of the catches will engage with thesides of the slots in the lips to draw and clamp the coupler partstogether, as shown at Fig. 2,.

The letter A designates an arm, which is projected from the iiangeF uponeach coupler part, and extended laterally, so as to be in line with thecentral passage O2, and so as to overlap and su'btend the rim of thefiange F of the other coupler part when the two latter are brought faceto face, as before described.

The letter I designates a screw-bolt that is threaded into the armA ofeach coupler part, and N a nut arranged on said bolt. Then said bolt isscrewed down in said arm, the lower end le2 thereof engages with thebevel B of each of the coupler parts and secures them as clamped by thelips and catches, as before described. The threads which operate thebolts I by means of the nuts N are -I OO prelerably puck-threads and soconstructed that a quarter-turn of the nuts will raise the bolt I fromout ol its engagement with the bevel B, or a quarter-turn in an oppositedirection will cause it to engage therewith.

The letter p2 designates a chamber made in the outward extension ot eachof the arms A, and S'l a spiral spring arranged therein to encircle thebolt I between its boss end c2 of said bolt and the top a3 of the saidchamber, so that said bolt israised against the face of said spring. Thefunction of this spring is to enable a quick thread to be used tooperate the bolt I, and to hold the latter down in engagement with thebevel B, so that the vibration orjars of a moving train will not throwit out of engagement. It desired, by using a slower thread on the bolt Iand nuts the spring SY1 may be omitted.

In the modication shown at Figs. 5, (i, 7, and 8, instead of the uut N,a lever-handle Il is on its inner end connected to the bolt I of eachcoupler part, and a chain C connects the outer end of this lever-handlewith the adjacent end of a railway-car. As thus made and arranged, theabutting faces of each of the coupler parts where having packing may bebrought together so as to abut, and by slightly rotating them oppositelythey are drawn closely together so as to be held in a steam or watertight connection by the oper ation of the screw-bolts.

y I am aware that a screw-bolt operated to engage with the beveled faceof coupler parts to canse them to engage is not new, broadly considered,and I disclaim the same apart from the improved manner in which Iconstruct the parts to use such factors, and this improved constructionot' the latter in combination with the other factors which I illustrateand describe.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination ol the coupler parts C and C2, each made with atail-piece V, a central passage-way O2, a packingface W, a iange F',having a bevel B, a wedge-form catch XV, a lip L, having the slot g, andan arm A.,l1av ing arranged therein the threaded bolt I, provided with anut N, con structed and arranged to operate, substantially in the manneras and for the purposes set forth.

2. The combination of the coupler parts (1 and C2, each made with thctail-piece V, a central passage O2, a packing F2, a flange lx", having abevel B, a wedge-form catch W', a lip L, having a slot g, and an arm A,constructed with the threaded bolt I, having the encircling spring S"and handle II and arranged to op erate substantially in the manner asand for the purposes set forth.

Signed at Troy, New `York, this 2d day of October, 1889, and in thepresence of the two witnesses whose names are hereto written.

JOHN W. MOORE.
